Silicon Bronze Sheet

Product Description

Silicon bronze is a low-lead brass alloy that is generally composed of 96 percent copper. The remainder can be made from silicon and a variety of other alloys such as manganese, tin, iron, or zinc. Silicon Bronze is known for its easy pouring ability, appealing surface finish and superior corrosion resistant properties, even when submerged in liquids and chemicals. Silicon Bronze was originally developed for the chemical industry but later expanded due to its good casting characteristics.

Product Application

Silicon bronze offers added strength in conjunction with the self-lubricity of silicon for excellent bearing and load properties. This is especially useful when silicon bronze is used for bearing cages, raceways and spacers specifically for the aerospace industry.
